RESUMO
INTRODUCTION: The increasing use of minimally invasive orthopedic procedures has led to a greater reliance on fluoroscopy, resulting in elevated radiation exposure for surgeons. This study aimed to evaluate the knowledge, awareness, and daily practices of orthopedic surgeons regarding radiation safety in an academic hospital. Understanding radiation safety is crucial to minimize patient exposure and prevent adverse effects on surgeons. METHODS: This cross-sectional study was conducted at the Department of Orthopedics of different tertiary care hospitals in Rawalpindi, Pakistan. Data were collected prospectively for two years, and a total of 505 participants, including residents, consultants, and operation theatre assistants, completed a questionnaire. The questionnaire was validated by experts and covered information on fluoroscopy usage, frequency of surgeries, awareness of radiation safety, and protective measures. Ethical approval was obtained, and data were analyzed using SPSS version 26.0. RESULTS: The majority of participants were male (74.1%), and the sample included various ranks of orthopedic surgeons. Only 56.2% of participants were aware of the usage of fluoroscopy, and 40.2% had read some research on the topic. While 44.6% used lead aprons for radiation protection, the usage of other protective measures and dosimeters was limited. The mediation analysis showed an insignificant indirect association between the rank of orthopedic surgeons, number of surgeries performed, and fluoroscopy usage as a mediator. Awareness and reading research on fluoroscopy were significantly associated with radiation protection. CONCLUSION: The knowledge, awareness, and daily practices of orthopedic surgeons regarding radiation safety in fluoroscopy use need improvement. The findings emphasize the importance of implementing training programs, providing radiation protection devices, and ensuring compliance with safety guidelines.
RESUMO
Objective The objective of this study was to evaluate the effectiveness of dexamethasone in treating postoperative pain in patients undergoing total knee arthroplasty (TKA). Methodology This randomized controlled trial (RCT) was completed over the course of two years (September 7, 2015, to September 6, 2017). In the course of their treatment for osteoarthritis of the knee, all of the patients who had primary unilateral total knee replacement (TKR) participated in the research. Under spinal anesthesia, each patient had medial para-patellar approach medial orthopedic surgery. Patients were assigned to group A or group B based on a random selection. Each of the groups consisted of 79 individuals. Group A was given dexamethasone through intravenous administration at a dose of 0.1 mg/kg before the operation. During the subsequent period of 24 hours, no more treatment was administered (control group). On a predesigned questionnaire, postoperative pain was measured using the visual analog scale (VAS) for pain. Functional results, duration of hospital stay, and complications were all recorded on the questionnaire (VAS). Analysis of data was carried out using the Statistical Package for the Social Sciences (SPSS) version 23 (IBM SPSS Statistics, Armonk, NY, USA). Results There were 158 patients in total in the study, out of which 98 were females and 60 were males in the group. The patients' average body mass index (BMI) was 26.94 ± 3.14 kg/m2. Patients in group A had lower postoperative analgesic and antiemetic needs and higher VAS scores and spent less time in the hospital than patients in group B. There were no postoperative problems in either group. Conclusion In patients undergoing TKA, the use of dexamethasone during and after surgery decreases pain, the need for analgesics, and the duration of hospital stay.
